What is causing my 1994 gmc jimmy to hessitate on


yep, but more than likely you need to replace your spark plugs and/or injectors.
go to the autowreckers and you can get a new fuel rail with used injectors or you can buy refurbished ones at napa or autozone that are cheaper than buying all new ones.

94 gmc jimmy will not start


You have to determine a few things. Are you getting spark at the plugs? Are you getting fuel to the injectors? You can also read the engine codes to see what codes are stored in there.

MOST LIKELY THE FUEL PUMP HAS FAILED, WHEN U TURN THE KEY TO RUN POSITION DO U HEAR A HUMMING NOISE FROM THE FUEL TANK? THIS NOISE WILL STOP IN ABOUT 5 SECONDS, U CAN HEAR IT BETTER BY TAKING OFF THE GAS CAP AND LISTENING THERE, IF U HEAR NOTHING THEN THE PUMP WILL HAVE TO BE REPLACED.

Hard start when cold/first start in morning


The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.

1994 jimmy fuel shutown @spider?


Hi

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.

There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.

Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.

Very best regards
